The Quick Read: When a short-term rental converts to a long-term rental, a DSCR lender stops counting booking revenue and re-bases qualifying income on a signed lease or the appraiser’s monthly market rent, then divides that figure by the full payment on the new loan, so the ratio usually shifts and often falls. DSCR, short for debt service coverage ratio, compares a property’s rent to its monthly housing payment.
- Income switches from booking history or a projection to a lease or appraiser market rent.
- On most files the lower of the signed lease and the appraiser’s market rent sets the number.
- The payment side is the new loan’s full payment, including taxes, insurance, and any association dues.
- Clearing the ratio is not the same as positive cash flow, because repairs, vacancy, and management sit outside the math.
- Run the ratio on both income bases before you pick a loan, so a conversion does not surprise you later.
Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Key Terms Defined
PITIA is principal, interest, taxes, insurance, and association dues, the full monthly housing payment that sits under the ratio.
Qualifying income is the rent figure a lender actually credits, which can differ from what the property earns on paper.
Haircut is the discount a lender applies to short-term rental revenue before it counts, to allow for vacancy and operating cost.
Form 1007 is the appraiser’s rent schedule for a one-unit property. It estimates monthly market rent on a traditional lease.
Form 1025 is the multi-unit version, used on two-to-four-unit properties.
Market rent is what the appraiser says the unit would rent for on a standard long-term lease.
Seasoning is the waiting period or track record a lender wants before it counts a result, such as months of hosting history.
How Is STR Income Counted Before You Convert?
Before conversion, lenders count short-term rental income through one of four routes: trailing booking history, a third-party projection, an appraiser’s short-term analysis, or a market-rent fallback. Each route gets a discount, and the discount is not a fixed rule. It varies by lender and by program.
| Method | Evidence | Typical caveat |
|---|---|---|
| Booking history | Platform and bank records | Needs a track record |
| Manager statement | Management company reports | Depends on manager’s records |
| Projection | Data-service estimate | Usually discounted harder |
| Market-rent fallback | Appraiser’s long-term rent | Often the lowest figure |
Across the network, the short-term rental programs we place files with generally expect about 12 months of hosting history and a credit score of 640 or higher. Purchase leverage on short-term rental collateral tops out at 75% LTV on the strongest files. LTV, or loan-to-value, is the loan balance as a percentage of the property’s value.
Refinances and cash-outs on short-term rental collateral run lower, up to 70% LTV. Those are program ranges, not promises, and they are subject to lender guidelines.
What Changes the Moment It Becomes a Long-Term Rental?
The income basis changes. A long-term rental is reviewed on a signed lease or the appraiser’s market rent, not on bookings or a projection. The history you built hosting guests no longer sets the number.
That is how STR DSCR income rules work in practice once a unit is leased. The 1007 is the tool the lender leans on. Fannie Mae’s appraiser guidance describes Form 1007 as the way an appraiser documents estimated monthly market rent on a single-family investment property. Agency rules do not govern DSCR loans, so that source helps only with the form’s definition.
Class Valuation, an appraisal management company, explains that the 1007 was built only to estimate long-term monthly rent. It adds that a 1007-based ratio often looks artificially low on a property that really operates as a short-term rental. After conversion that mismatch goes away, because the property now really is a long-term rental.
McKissock, an appraisal education provider, reports that an appraiser may not multiply a nightly rate by 30 to produce monthly rent on this form. It also notes that the lender, not the appraiser, makes the final income determination.
Think of it as one story per file. If you tell the lender the property is a stabilized long-term rental, the file needs lease-based support, not a booking calendar. Mixed narratives slow files down.
Lease or Market Rent: Which Number Sets Your Ratio?
On most files the lower of the signed lease and the appraiser’s market rent sets your ratio. An above-market lease does not lift the number, and a below-market lease pulls it down.
| Situation | Number the lender leans on |
|---|---|
| Tenant in place, lease at market | Lease and market rent agree |
| Lease above market | Market rent, on most files |
| Lease below market | The lease, on most files |
| Vacant after hosting | Appraiser’s market rent alone |
| Furnished short lease | Often market rent, not the premium |
A short-term guest agreement is not a lease. It runs on nightly terms and includes furniture and equipment. A lender wants a standard lease at market rent. A furnished three-to-six-month agreement may not count as that lease, and whether a program credits any furnished premium depends on its guidelines.
You also cannot argue the 1007 figure upward with your own rent research. If you believe the comps are wrong, the route is a reconsideration of value or a second appraisal.
Worked Example: Same Property, Two Income Bases
Here is a modeled illustration, not market data. Assume the payment is identical in both cases, which holds when you refinance into the same loan structure. Only the income basis changes.
| Item | STR basis | LTR basis |
|---|---|---|
| Qualifying income | Booking-based, after haircut | Market rent, 20% lower |
| Payment | Same | Same |
| Ratio | About 1.30x | About 1.04x |
| Cushion over 1.00x | Comfortable | Thin |
If the long-term figure comes in 25% below the STR figure, the same property lands near 0.98x. That falls below 1.00. Break-even is the rent that exactly equals the payment, and every point under it needs a plan.
Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Either way, qualification is subject to lender guidelines, credit approval, and property review.
This ratio is also not cash flow. DSCR compares rent to PITIA only. A property can clear 1.00x and still lose money after repairs, vacancy, management, utilities, and capital spending.
What Is the Order of Operations for a Conversion?
The cleanest conversion follows a set order. Document the lease before you apply, because it changes what the underwriter can credit.
1. Stop taking new bookings and honor the reservations already on the calendar.
2. Sign a standard lease at market rent, or leave the unit vacant if you plan to rely on the appraisal.
3. Update insurance to match the new use.
4. Order the appraisal, which sets both value and market rent.
5. Compare the ratio against the program floor before you commit.
6. Submit the file with the lease and appraisal side by side.
Overlap is the common trap. A lease that starts while old guest stays remain on the calendar muddies the file. It gives the underwriter two stories about the same unit.
The documents differ by scenario:
- Vacant after hosting: the appraisal with rent schedule, insurance, reserve statements, and entity documents if you hold in an LLC, subject to program terms.
- Tenant in place: all of the above plus the signed lease and proof of deposit.
- Mid-lease: the lease with its remaining terms, which the lender reads for rent and for any early-exit clauses.
A DSCR file needs no W-2s, traditional personal-income documentation, or pay stubs, since it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
How Does the Payment Side Change?
The denominator is the new loan’s payment, not the old one. The old loan’s payment no longer matters. What matters is the new principal, interest, taxes, insurance, and dues.
Insurance often changes with the use. A policy written for short-term guests is not the policy a long-term landlord carries. On condos, association dues sit inside the payment, and association rules can limit leasing terms.
That is why a conversion can move both halves of the ratio at once. Income falls while the payment may shift too. Run both numbers fresh.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What Do Leverage and Credit Look Like After Conversion?
Once a property is a leased long-term rental, it moves into the standard rental tiers. Most purchase files land at 75% to 80% LTV on a standard long-term rental. Select high-leverage programs reach 85% LTV with roughly a 700 score. A cash-out on a standard long-term rental tops out around 75% LTV, versus 70% on short-term-rental collateral, and about 6 months of seasoning is the common expectation. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Credit also shifts. A 620 floor exists in parts of the network. Most long-term programs want around 660, and 700 or higher unlocks the strongest leverage tiers. Reserves vary by lender, leverage, loan size, and transaction type, and they commonly run around 6 months of PITIA.
Here is the conversion catch. A lower rent used for lender review shrinks the loan that fits at a given coverage floor. On a cash-out, that can cap the proceeds before the LTV limit does.
A larger down payment lowers the payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Lendmire’s complete DSCR loans guide walks through those tiers in more detail.
Where Does the General Rule Break?
The re-basing rule holds on most files, but a few situations bend it.
Mid-term rentals. Stays of 30 days or longer are often used to sidestep short-term permit rules. A furnished mid-term rental may still be underwritten on the appraiser’s long-term market rent. Whether a program credits the mid-term premium depends on its guidelines.
Multi-unit properties. On two-to-four units, Fannie Mae’s selling guide lists Form 1025 for the appraisal. Unit-level figures are summed, and some units may be leased while others sit vacant. Again, the agency source helps only with form names.
Short history. A property with a thin booking record may have been underwritten on a projection. After conversion that history stops mattering for coverage, though it can matter again if you switch back to hosting. Expect to re-establish a track record, since short-term programs generally want about 12 months of hosting history.
Sub-1.00 coverage. If lease-based rent falls short of the floor, a select-lender path takes coverage below 1.00 with leverage and terms adjusted. Other levers include a larger down payment, a smaller balance, or a different program tier.
Condos and covenants. A property that cannot run as a short-term rental often still works as a long-term one. Check the association’s lease rules before you assume it does.
Interest-only and longer terms. Interest-only periods and 40-year terms are available through select lenders in the network. They lower the payment and can lift the ratio. They change the file’s terms, so they are options to price, not shortcuts.
Convert First or Refinance First?
This is a genuine toss-up that depends on the property. Refinancing first on short-term income can show a stronger ratio, but it ties your loan to a basis you plan to leave. Converting first gives a cleaner file, but a lower number.
| Path | Upside | Risk |
|---|---|---|
| Refinance on STR income, then convert | Higher qualifying income | Lease may conflict with the loan’s basis |
| Convert, then refinance on lease or market rent | Clean, consistent file | Lower ratio, smaller loan |
| Hold as STR and skip the conversion | Keeps booking income | Needs ongoing hosting record |
If a property only works on short-term income, a conversion later may not refinance cleanly. The stronger play is usually to test both bases before choosing a path. Each property is also underwritten on its own income against its own payment, so a strong short-term rental cannot offset a weak long-term one.
Longer stays can also cut cleaning, turnover, and guest-acquisition costs, which may improve real cash flow even as the coverage figure drops. The ratio and the cash flow measure different things.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Does my STR history carry over after I convert?
Not for coverage. Once the property is leased long term, qualifying income comes from the lease or the appraiser’s market rent. The history can matter again if you return to hosting, because short-term programs generally look for about 12 months of hosting experience.
Will my DSCR drop after I convert?
In most markets, yes, because market rent is usually lower than a discounted booking figure. The size of the drop depends on the property and the program. Run the ratio on both income bases before you apply.
Can I use a lease that is above market rent?
On most files an above-market lease does not lift the ratio, because the lower of the lease and market rent sets the number.
Do I need a new appraisal?
Yes, in most cases. The appraisal sets value for LTV and market rent for coverage. Use Form 1007 on one unit and Form 1025 on two to four units.
What if coverage falls short after conversion?
You have levers: a larger down payment, a smaller balance, stronger rent support, or a different program tier. A select-lender path takes coverage below 1.00 with leverage and terms adjusted. Eligibility stays subject to lender guidelines and credit approval.
